METHOD OF GOOKING ARTICLES OF FOOD.'

Specification of Letters Patent.

Patented Apr. 30, 1912.

Application filed March 31, 1909. Serial No. 486,847.

without any additions of fat or water, into a greaseand water-tight bagof poor heat conducting material, closing the bag and sealing the samewith some adhesive substance having no .injurious effect upon the food,for example, with flour mixed in water, and then subjecting the bag toindirect heating. For this purpose the bag with its contents is placedinto an airtight receptacle adapted to withstand great heat and of suchdimensions that the bag does not contact with the walls of saidreceptacle; Preferably, the bag is placed on a grid within thereceptacle and above the bottom thereof. The article of food; meat,fish, poultry, or the like, treated in such manner, although cookedsolely with its own fat and water contents, without anyaddition of fatand water, is particularly juicy and tender, retaining its specificflavor, albumin-contents etc.

The bag used in the performance of the process must be greaseandwater-tight, not affected by heat, and such that it will not impair theflavor of the food. The bag may suitably be made of some fibrousmaterial which is already greaseand water-tight, or is so renderedsubsequently.

Parchment paper cannot be penetrated by grease or water, but the heatmay exert the proper influence therethrough upon the article to beprepared. Any adhesive substance which neither in cold, heated, dry normoist condition impairs the flavor of the food, may be used, such as forexample flour mixed in water, or the like.

Suitable apparatus for performing the described process is illustratedby way of example in the accompanying drawing in which Figure 1v is aninverted plan. 2a

The apparatus comprises a receptacle, the

Jbot-tom a and side-walls b of which are made in one piece, and jointedwith the cross walls '0 solely by folded seams as shown in Fig. 3. Thereceptacle may be suitably strengthened by a strap d held by anoverturned part c ofthe walls 6. To one side of this strap may beattached a catch f, while a cover 9, made similar to the under portion,is hinged to the other side of the strap, the latter serving as anabutment for the cover, when in closed position.

A receptacle of such construction may be subjected to great heat withoutimpairing its air-tightness. Inside said'receptacle is placed a grid 1"provided with feet It and handles e made Without soldered joints. Thearticle of food m is contained within the bag is the inlet opening ofwhich is tightly closed and sealed up with. an adhe'sive substance. Thegrid 1' must be of such dimensions that the bag 70 does not contact withany of the walls of the receptacle so as to prevent burning of the food.The inclosing of the food article into the flexible bag presents thefurther advantage that at any time on opening the cover the stage of thecooking may be easily ascertained by, pressing the article with a forkor pin, but preferably with a blunt instrument.

Having now described-my invention what I claim and desire to secure byLetters Patent of the United States is The method of cooking articles offood, which consists in inclosing the articles in a paper bag which isgrease and water tight, closing the bag and subjecting the same toheated air in an airtight receptacle, while the bag is free of contactwith the sides or walls of the receptacle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
